- (void)viewdidload { [super viewdidload]; self.locationmanager = [[cllocationmanager alloc]init]; self.locationmanager.delegate = self; if ([self.locationmanager respondstoselector:@selector(requestalwaysauthorization)]) { [self.locationmanager requestalwaysauthorization]; } [self.locationmanager startupdatinglocation]; //initialize map , specifiy bounds self.mymapview =[[mkmapview alloc]initwithframe:self.view.bounds]; //specifcy resizing self.mymapview.autoresizingmask = uiviewautoresizingflexiblewidth | uiviewautoresizingflexibleheight; //show user's location , set tracking mode self.mymapview.showsuserlocation = yes; self.mymapview.usertrackingmode = mkusertrackingmodefollow; //add view!! [self.view addsubview:self.mymapview]; }

and here function want call

- (void)requestalwaysauthorization { clauthorizationstatus status = [cllocationmanager authorizationstatus]; // if status denied or granted when in use, display alert if (status == kclauthorizationstatusauthorizedwheninuse || status == kclauthorizationstatusdenied) { nsstring *title; title = (status == kclauthorizationstatusdenied) ? @"location services off" : @"background location not enabled"; nsstring *message = @"to utilize background location must turn on 'always' in location services settings"; uialertview *alertview = [[uialertview alloc] initwithtitle:title message:message delegate:self cancelbuttontitle:@"cancel" otherbuttontitles:@"settings", nil]; [alertview show]; } // user has not enabled location services. request background authorization. else if (status == kclauthorizationstatusnotdetermined) { [self.locationmanager requestalwaysauthorization]; } } - (void)alertview:(uialertview *)alertview clickedbuttonatindex:(nsinteger)buttonindex { if (buttonindex == 1) { // send user settings app nsurl *settingsurl = [nsurl urlwithstring:uiapplicationopensettingsurlstring]; [[uiapplication sharedapplication] openurl:settingsurl]; } }

-(void)locationmanager:(cllocationmanager *)manager didchangeauthorizationstatus:(clauthorizationstatus)status

this delegate method location service can authorizationstatus status.such kclauthorizationstatusdenied

you call

[self.locationmanager requestalwaysauthorization];in viewdid load,and monitor authorizationstatus in delegate method above,if user deny location service,show alertview
